The D4 digital 4 channel wireless system was designed as a special purpose system for location production in film and television. The typical application for this system would be for the D4T transmitter to transmit up to 4 channels of audio from a portable mixer to the D4R receiver mounted on a video camera. The D4 system is designed to receive line level analogue audio signals and AES/EBU digital audio signals and can be set up as a 2 channel or 4 channel system.

The in/out options can be configured in the following:

Digital in/Digital out (< 1 mS latency)

Digital in/Analog out

Analog in/Digital out

Analog in/Analog out (2.2 mS latency

In the 4 channel mode, the D4 system operates on one of four 4 MHz channels in the 902 to 928 MHz band. Each channel carries four separate, digitally multiplexed with a common carrier. The audio is 24 bit/48kHz and ruler-flat, with a 20-20,000 Hz frequency response. This is some great sounding wireless, suitable for any professional application. The LCD makes setup simple and very user friendly. The D4 will oprerate on any DC source between 9-16 volts. Operating range is similar to Lectrosonics Digital Hybrid systems.

Housings and panels are machined aluminum with electrostatic powder coated and anodized finishes and laser etched marking for durability.
